ARTHUR 1B. MOJDINE, OF RACINE, WISCONSIN.

AUXEMRY TANK AND MEANS FOR MAINTAINING THE TEMPERATURE OF A GIRCULATING FLUID.

5 of Wisconsin, have invented certain new and useful Improvements in an Auxiliary Tank and Means for Maintaining-the Temperature of a Circulating Fluid, of which the following is a description.

My invention relates to the cooling system for any mechanism where there is liability of annoyance from great changes of temperature of the circulating fluid when the mechanism is not in operation, such for example, as the internal combustion motors used on automobiles or other devices.

The object" of my invention is to provide a simple, reliable, inexpensive and convenient device of the kind described wherein 2c the circulating fluid is removed from the system when the mechanism is not in service and temporarily stored in a thoroughly protected and insulated receptacle wi h means or returning the fluid to the circulating system as soon as the mechanism is started. To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

tration I have shown my improvement in connection with the internal combustion motor and circulating system of an automobile in which 1 is the motor, of the usual or any preferred construction havingan exhaust manifold 2 substantially of the usual or any desired form. A radiator 3 is connected to the motor 1 by a supply pipe i and a return pipe 5 for conducting the fluidfrom the radiator to the water jacket of the motor and returning the same to the radiator, all constructed and arranged substantially in the usual or any preferred manner.

y improvement consists in the receptacle 6, connected by a pipe .7 preferably to the lowest portion of the circulating system so as to form a convenient, direct passage from the radiator to the receptacle adapted to drain all fluid from the radiator and the system to which it is connected into the recep- .tacle.-- The size of the receptacle 6 is preferably sufficient to receive all of the fluid from the system leaving a slight open space 8 at the "top of the receptacle. In the preferred construction the pipe 7 extends into the receptacle 6 substantially to the bottom thereof as at 9 and a tube 10 extends from the manifold 2 to the space 8in the receptacle adapted to conduct a portion of the burned gases from the manifold 2 to the receptacle- If the preferred construction also a casing 11 is connected to the part 8 of the rece tacle and incloses the pipe 7 and ex ten s along the pipe for any desired distance with a valve 12 at the outer end of the casing so that if desired the valve 12 may be opened and permit the hot ases from the manifold 2'to flow by the pipe 10 into the space 8, thence through the casing 11 around the pipe 7 to the outer end of the casing and escape through the valve 12 thus heating the pipe and the contents thereof. The exterior of the receptacle 6 and that portion of the pipe 7 between the outer end of the easa portion of the hot gases in the exhaust manifold are conducted into the space 8 by the pipe 10 which is of sufficient capacity to permit a slight escape through the valve 12 and yet maintain a sufficient pressure in the receptacle 6 to force the liquid fromthc receptacle through the pipe 7 into the radiator 3 thus filling the radiator and circulating system and holding the liquid in the system as long as the motor is in operation. Where the pressure in\ the exhaust manifold is unusually low, the velocity of the escaping gases may be utilized to increase the pressure in the receptacle 6 by forming the end of the pipe 10 as shown in Figs. 6 and 7 so that the open end-of the pipe 10 ls'positioned so as to receive aportion of the moving gases and thus increase the pressure in the pipe 10. Under ordinary conditions the valve 12 may be closed thus preventing the hot gases from passing through the casing 1 to heat the pipe 7. Where however, the parts are exposed sufiiciently to chill the parts belowthe freez mg point it is desirableto open the valve 12 thus heating the liquid as it'passes through the pipe 7 into the system and preventing undue chilling or freezing. Since the liquid is removed from the water jacket-of the motor also the parts will arrive at a satisfactory operating temperature much more quickly than .where the water jacket is filled with liquid, thus rendering the starting of the motor much easier.

In the preferred form also a check-valve 16 1s provided in the pipe 7 below the radiator 3 so that during summer weather or at normal temperatures the valve will automatically prevent the escape of the fluid from the system. As shown a stem 17 extends through the wall of the valve 16 and engages the closure 18 so that when desired the closure may be held at any desired distance from its seat thus permitting the escape of the fluid from the system to the receptacle 6 to be regulated to suit the varying operating conditions.

7 In this form preferably the closure 18 is longitudinally movable upon the stem 17 a sulficlent amount to permlt the closure. 18 to recede sufficiently to permit a full sized opening through the valve and not interfere with the movement of the liquid from the receptacle 1nto the system.

In the form shown in Fig. 3 the casing 11 is omitted and the insulated covering-of the plpe .7 extends the entire length of the pipe to protect the fluid in the pipe from sudden changes of temperature.

In the formshownin Fig. 4 the valve 20 below the radiator 3 isa clutch valve of the usual or any preferred form adapted to pernnt the free escapeof liquid from the radiator to the tank 6 but to prevent its movement in the opposite direction.

In thls form a pipe 21 vpreferably connects the valve 20 to. a pipe 22 extending into the tank to a point near its bottom, which is also connected by a pipe 24 to the upper water connection 5 between the motor 'jacket and the radiator. The remainder of scribed. When thus constructed the liquid in the cooling system flows into tank 6 when the motor is stopped as hereinbefore explained. When the motor is started however the liquid is forced from the tank through the pipes 22 and 24 and flows directly to the cylinder water jackets and thence into the radiator through the lower water connection 1, thus heating the liquid before it enters the radiator and preventing any danger of trouble due to injecting cold water into a very cold radiator.

While my improvement is intended primarily to guard against freezing or extremely low temperatures of the circulating liquid for the cooling system of internal combustion motors, it also serves a very important and useful purpose in warm weather, viz. that of a storage receptacle for liquid so that the motor may be operated for long periods in locations where a supply of the liquid is inaccessible.

Having thus described my invention it is Aahe temperature of said mechanism and a system including a radiator forcontaining and directing said fluid to said mechanism, in combination with a receptacle adapted to receive the liquid from said system, a passage connecting said receptacle to said system and pneumatic means controlled by the operation of said mechanism for expelling the "liquid from saidreceptacle and maintaining the same in said system.
